Packaging clip

ABSTRACT

A packaging clip having an end tab that aids in the quick removal of the packaging clip from an end board without damaging either the clip or the end board. The packaging clip can be placed to receive a single end board or to receive adjoining end boards. Each packaging clip is capable of gripping the end board received therein in the event that the fit is too loose. Packaging clips are used for receiving and stabilizing the placement of multiple end boards on a pallet and for the alignment of the ends boards with each other.

This application claims the priority benefit of U.S. Provisional PatentApplication Ser. No. 61/069,798, filed Mar. 18, 2008.

BACKGROUND OF THE INVENTION

The present invention pertains to packaging and palletized packages,generally, and more particularly to a novel removable and recyclablepackaging clip used in such packaging and packages. The recycling ofpackaging clips will provide cost savings to the packaging industry, andmore importantly, will provide an environmental benefit.

Packaging clips have been used in the textile industry for packing largerolls of textiles, such as paper or plastic film. Use of packaging clipsis a safer and more secure way to load and ship a pallet of rolls oftextiles for shipment to customers when used in connection withrectangular or square rigid end boards connected to the ends of eachroll with roll plugs. The flat edges of end boards, prevent the rolls oftextiles from rolling as they sit on a flat surface. By using endboards, rolls of textiles may be elevated from the pallet, spaced apartfrom other rolls, and more securely stacked on a pallet than can beaccomplished by attempting to place rolls directly on a pallet withoutend boards. Without end boards, rolls are susceptible to becomingengaged with each other and/or becoming damaged or rolling off thepallet, thus requiring greater attention and effort to ensure secureplacement on the pallet. Packaging clips are used to secure end boardsto a pallet. U.S. Pat. No. 6,592,309 to Baughey discloses and claims analternating U-channel packaging clip used in such a packaging system.The disclosure of this patent is hereby incorporated by reference, inits entirety, into this specification.

In general, upstanding rectangular or square end boards are secured tothe ends of rolls of textiles by roll plugs, and multiple rolls arestacked on a pallet in a spaced relationship. End boards keep the rollsseparated and connected to the pallet. In order to stabilize the specialrelation of end boards on the pallet, U-channel packaging clips aresecured to the pallet and end board edges are inserted into the clips,which then act as rails to limit the lateral movement in two directions.The remaining directions of lateral movement are limited by polymeric ormetal banding securing the rolls to the pallet.

Packing clips now commonly used for stacking rolls of textiles areremoved after use so the end boards may be recycled for re-use. Therecycling of the packaging clips now commonly has been limited by theirdesigns, an example of which is shown in Prior Art FIGS. 7 a and 7 b,which has increased the time-consuming removal process and has tended tocause damage to the end boards. Thus, it is highly desirable to providea new packaging clip design and method of use that will permit easierrecycling of the most commonly used packaging clips and that also willhave environmental benefits, energy savings, and produce waste reductionand raw material conservation in recycling of packaging clips.

SUMMARY OF THE INVENTION

It is therefore an object of the invention to provide a new and improveddesign for a packaging clip that enables its easier recycling. Sincepackaging clips vary in widths and methods of being secured to endboards, the specific design must be universal for all industrial andcommercial uses, and must provide a fast method of removing thepackaging clip from end boards without destroying the packaging clip orthe end boards. The novel design for a recyclable packaging clip of thepresent invention allows the packaging clip to be put in to use, takenoff, and recycled all without damage to the either the packaging clip orend boards.

Novel end tabs of the packaging clips of the present invention replacethe side tabs present on the most commonly used packaging clips. Thenovel end tabs of the present invention will enable recyclers and endusers to remove packaging clips by providing a space between thepackaging clip and end board to engage a tool under the tab to pry thepackaging clip free from an end board, thereby providing a ready meansfor reuse of both the packaging clips and the end boards withoutdamaging either. Because the novel end tabs of the packaging clip of thepresent invention will facilitate ease of removal of the packaging clipfrom an end board, packaging clip and end board recycling will bepromoted, which will provide environmental benefits, energy savings,waste reduction and raw material conservation

One embodiment of the present invention is a packaging clip thatincludes a set of novel downwardly protruding end tabs formed from endedges of the middle support of the packaging clip. The end tabs protrudedownwardly from each end of the middle support to form a raised slotprofile into which a wedging tool may be inserted. The raised slotprofile thus enables a tool to be engaged between the packaging clip andan end board to pry the packaging clip from the end board, using the endboard as the lever point for the tool.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Referring now to the Figures, the novel packaging clip 12 of the presentinvention has upstanding receiving members 115. The receiving members115 comprise two upstanding free edges 117, 118 extendingperpendicularly from a middle support 125, thereby forming a U-shapedclip 12 (FIG. 5). U-shaped receiving channel 145 is generally defined bythe free edges 117, 118 of the receiving members 115 oppositely disposedfrom the middle support 125, into which the receiving members 115 willreceive an end board (not shown). The middle support 125 has two endedges 126, 127 at opposite ends of packaging clip 12.

Though one of the end edges of the middle support 125 is shown in FIGS.5 and 6, both of the end edges 126, 127 of the middle support 125 havean end tab 10. The end tabs 10 are formed from the middle support 125and protrude downwardly from the U-shaped receiving channel 145 createdby the receiving members 115 and the middle support 125. The end tabs 10can extend the width of or less than the end edges 126, 127 of themiddle support 125. In one preferred embodiment to date, the end tabs 10protrude downwardly a distance approximately equal to the thickness ofthe middle support 125.

In one preferred embodiment shown in FIGS. 5 and 6, the end tabs 10 areformed by deformation of the middle support 125 during the clip 10forming process. In another preferred embodiment shown in FIGS. 1-4, theend tabs 10 are formed by cutting notches in the end edges 126, 127 ofthe middle support 125 followed by a forced bending process that deformsthe tab portion created by the notches downwardly and away from thereceiving channel 145. In yet another preferred embodiment, the cuttingand forming steps can be part of a single process.

As shown in FIGS. 1-3, within the middle support 125 are a number ofsemi-perforated punches 165. These punches 165 start on the innersurface 135 of the middle support 125 and create burrs 166 on the outersurface 136 of the middle support 125. The burrs 166 are structured toengage adjacent end boards (not shown) during stacking. In oneembodiment, the burr 166 height is one-eighth of an inch. In others, theheight is one-sixteenth to one-quarter of an inch. The burr 166 heightcould be greater than the end tab 10 height.

A second set of punches 185 and resulting burrs 186 are located in themiddle support 125. These punches 185 begin on the outer surface 136 ofthe middle support 125 creating burrs 186 on the inner surface 135. Inone preferred embodiment, the burrs 186 have an effective height ofapproximately one-sixteenth of an inch. The burrs 186 are structured toassist in defining a slot profile 14 between the clip 12 and an endboard (not shown).

The slot profile 14 aids in allowing a wedging tool to slide between themiddle support 125 of the clip 12 and an end board when the clip 12 isassembled to an end board. The tool should be allowed enough access toprevent damage to the clip 12 and an end board during removal. The toolcan be something as readily available as a flat-head screwdriver, butcan also be a specially designed shape and material to minimize any typeof damage to the clip 12 or an end board during removal.

In another preferred embodiment as illustrated in FIGS. 1-3, thereceiving members 115 have a length of between 4 and 8 inches. In yetanother preferred embodiment as illustrated in FIG. 2, the middlesupport 125 of the clip 12 is between ¾ of an inch and 1¼ inches inwidth. In still another preferred embodiment, the thickness of anyportion of the material of the clip 12 is no more than ⅛ of an inch. Inother preferred embodiments as illustrated in FIG. 4, the upstandingfree edges 117, 118 of the receiving members 115 extend from the middlesupport 125 to a height between ¾ of an inch and 2 inches. In yet otherpreferred embodiments illustrated in FIG. 2, the end tabs 10 extend thewidth of the middle support 125. While for still others, the end tab 10width is between ⅝ inch and 1¼ inch. The packaging clip 12 is formed ofone continuous piece of stamped metal. In other specific embodiments,the metal with which the clip 12 is manufactured is iron based. In yetother specific embodiments, the iron based metal is resistant torusting. In other specific embodiments, the metal is galvanized. In yetspecific embodiments, the metal is stainless steel. While specificembodiments of the invention have been shown and described herein forpurposes of illustration, the protection offered by any patent which mayissue upon this application is not strictly limited to the disclosedembodiment; but rather extends to all structures and arrangements whichfall fairly within the scope of the claims which are appended hereto.
